SPECIFICATION forming part of Letters Patent No. 319,817, dated June 9, 1885.

To @ZZ whom it may concern:

Be it known that I, PARKER P. HOGUE, a citizen of the United States, and a resident of Sandy Lake, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Inspirators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, v and in which- Figure l is a perspective view of my irnproved inspirator. Fig. 2 is a vertical sectional view of the same; and Fig. 3 is a detail view.

The same letters refer to the same parts in all the figures.

This invention relates to inspirators or injectors forsteam-boilers; and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will bel hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates the casing of my improved inspirator,- which is provided near its lower end with a steam-entrance, B, connected with the steamspace ofthe boiler by means of a tube equipped with an ordinary stop-cock.

A tube, E, which is likewise equipped with a stop-cock, F, connects the upper end of the casing with the water-space of the boiler.

One of the sides of the casing is provided with a water-entrance, G, connected with the water-supply, and an overflow, H, in which is transversely arranged a three-way cock, K, adapted to connect the overflow with the passages I and J.

The casingA is provided between the waterentrance and the overflow with an interior screw-threaded flange, L, into which is screwed a barrel, M, having at its lower end a flange, N, bearing against a shoulder, O, formed interiorlyin the casing A directly above the steamentrance. The barrel M has a central perforation or passage, P, terminating at its upper end in a nipple, Q, and the side of the said barrel is provided with a recess, R, registering -with the water-entrance, and from which perforations or passages S and I extend through the barrel, respectively, to the lower and upper ends of the latter.

The casing A has between the passages I and J an interiorscrcw-threaded flange, U, in which is secured an upwardlyextending tube, V, the lower end of which is entered by the nipple Q of the barrel M.

The lower end of the casing A has a plug, W, through which passes astem,X,having a valve, Y, adapted to close the lower end of the perforation P of the barrel M, which is ground to form aseat for the said valve. A stuffing-box, Z, surrounding the valve-stem, issecured upon the plug W.

The operating lever or handle A2 ofthe th reeway cock K isconnected by a pivoted rod, B2, with the valve-stem X, which latter may thus be operated simultaneously with the said threeway cock.

g From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood'. When the threeway cock K is open,the valveY closes the lower end of the passage P, as shown in Fig. 2 of the drawings. If, while the valve is in this position, steam is admitted through the passage B, it will pass through the passage S, causing the water to rise and enter through the passage G, whence it passes through the recess R and passages T and J to the overflow. The three-way cock is now turned so as to close the passages I J and the overflow and open the valve Y,thus admitting of the passage of the steam through the passage P, when it will serve to force the water through thetubesV and E into the boiler.

The overflow being connected with the waterspace of the boiler through the passage I and tube E, may serve, whendesired, as a hot-water overow. Y

Inspirators as ordinarily constructed have separate casings for the ejecting and injecting f devices, making the construction cumbersome and expensive, and more liable to get out of roo order. By my invention the entire device is comprised within a single casing, and the conthe said water-tube, a recess registering with the water'entrance, and perforations or passages extending upwardly and downwardly from the said recess, and a valve arranged to close the lower end of the central passage of the said barrel, which is located directly above the steam entrance, substantially as and for the purpose herein set forth.

2. In an inspirator,l the combination of a casing having a steamentrance, water-entrance, overflow, and connection with the wa.- terspace of a boiler, substantially as described, and provided with passages I and J, the barrel M, having recess R, and passages P, S, and T, the tube V, three-way cook K, valve Y, and a pivoted rod connecting the stem of the said valve with the handle of the three-way cock, all constructed, arranged, and operating 'substantially as and for the purpose herein set forth. i

In testimony thatI claim the foregoing as my own I have hereunto aixed my signature in presence of two witnesses.
